FIGS. 3A and 3B are drawings illustrating a spherical coordinate systemdefined in a display device DD. FIG. 4 is a graph illustrating theamount of change in color coordinates of a white image generatedaccording to measurement points.

As shown in FIGS. 3A and 3B, the spherical coordinate system may bedefined in the display device DD. The origin of the spherical coordinatesystem may be aligned with the center of a display area 1000A. Thespherical coordinate system may be used to distinguish points formeasuring display quality of the display device DD, and the points maybe displayed as coordinates of the spherical coordinate system.

The coordinates of the spherical coordinate system are represented as(r, θ, ϕ). “r” denotes the distance from the origin to the measurementpoint, θ denotes the angle formed by a z-axis (or a normal axis of thedisplay device DD) and the straight line defined between the origin andthe measurement point, and ϕ denotes the angle formed by the straightline in which a straight line defined between the origin and themeasurement point is reflected in an xy plane (or the front surface ofthe display device DD) with respect to an x-axis (or the horizontal axispassing through the center of the display device DD). For convenience ofdescription, θ is defined as a viewing angle and ϕ is defined as anazimuth angle. For example, x-axis and y-axis may be in the firstdirection DR1 and the second direction DR2, respectively, and z-axis maybe in the third direction DR3 which is perpendicular to the planedefined by the first direction DR1 and the second direction DR2.

FIG. 3A illustrates five measurement points P1 to P5. First to fifthviewing angles θ1, θ2, θ3, θ4, and θ5 may be spaced apart from eachother by a certain angle to be measured. The first to fifth viewingangles θ1, θ2, θ3, θ4, and θ5 of the first to fifth measurement pointsP1 to P5 may be 0°, 15°, 30°, 45°, and 60°, respectively. Alternatively,the first to fifth viewing angles θ1, θ2, θ3, θ4, and θ5 of the first tofifth measurement points P1 to P5 may be 0°, 20°, 40°, 60°, and 80°,respectively. Alternatively, the first to fifth viewing angles θ1, θ2,θ3, θ4, and θ5 of the first to fifth measurement points P1 to P5 may be0°, 10°, 20°, 30°, and 40°, respectively. Eighth azimuth angles ϕ1 to ϕ8are illustrated as an example in FIG. 3B. The eighth azimuth angles ϕ1to ϕ8 are 0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°.

FIG. 4 illustrates first, second, and third graphs GP1, GP2, and GP3.Each of the first, second, and third graphs GP1, GP2, and GP3 includesthe amounts Δu′ and Δv′ of change in color coordinates of a white imagemeasured at the five measurement points P1 to P5. The five measurementpoints P1 to P5 are measured in the same distance r. Color coordinates(u′, v′) of the CIE 1976 color coordinate system of a white imagemeasured at a point of (r, 0°, 0°) is a reference value.

The five measurement points P1 to P5 of the first graph GP1 have a firstazimuth angle ϕ0 and have different viewing angles θ. As going from thefirst point to the fifth point, the viewing angle θ uniformly increases.The second graph GP2 and the third graph GP3 have a second azimuth angleϕ20 and a third azimuth angle ϕ30, different from the first azimuthangle ϕ10 of the first graph GP1, respectively. The first azimuth angleϕ10 may be smallest, the second azimuth angle ϕ20 may be greater thanthe first azimuth angle ϕ10 by 45°, and the third azimuth angle ϕ30 maybe greater than the second azimuth angle ϕ20 by 45°.

It may be seen that the amounts Δu′ and Δv′ of change in colorcoordinates at the fifth measurement point P5 of the third graph GP3 isrelatively large. In other words, a white image is recognized as areddish white image by a user who looks at the white image at a point ofthe third azimuth angle ϕ30 and the fifth viewing angle θ5. As such, aphenomenon in which the amounts Δu′ and Δv′ of change in colorcoordinates are large at only a specific point is referred to as whiteangular dependency (WAD).

A white image generated by a display panel 100 shown in FIG. 2 issubstantially a result of mixing first color light generated by a firstcolor pixel, second color light generated by a second color pixel, andthird color light generated by a third color pixel.

An interference phenomenon may occur in a process of passing through astructure located at an upper side of the pixel in the first colorlight, the second color light, and the third color light. Because ofmoving to another optical path depending on a viewing angle θ, aninterference phenomenon may differently occur depending on the viewingangle θ and the amounts Δu′ and Δv′ of change in color coordinates mayvary with the viewing angle θ. Because an interference degree of each ofthe first color light, the second color light, and the third color lightdifferently occurs depending on an optical path, the white image may beshifted to a certain color.

Because of a structural characteristic of the display device DD, forexample, arrangement of optical axes of the optical film, the amountsΔu′ and Δv′ of change in color coordinates may be larger at only ameasurement point having a specific azimuth angle ϕ.

The white image may be recognized as a reddish white image, a bluishwhite image, or a greenish white image according to the direction of achange in color coordinates. Furthermore, the white image may berecognized as a reddish white image, a bluish white image, or a greenishwhite image according to an azimuth angle ϕ.

Hereinafter, a description will be given in detail of a principle ofreducing white angular dependency (WAD) in the present disclosure.

Each of the second sensing electrodes E2-1 to E2-4 may include sensingpatterns SP2 and bridge patterns CP2 (or connection patterns). The twosensing patterns SP2 adjacent to each other may be connected with thetwo bridge patterns CP2 through a contact hole CH-I (refer to FIG. 6A)penetrating the second insulating layer 200-IL2 (refer to FIG. 6A), butthe number of bridge patterns is not limited thereto.

FIG. 6C illustrates an enlarged view of the sensing pattern SP2 todescribe the first sensing electrodes E1-1 to E1-5 and the secondsensing electrodes E2-1 to E2-4, which have the mesh shape shown in FIG.6B. Other portions of the first sensing electrodes E1-1 to E1-5 and thesecond sensing electrodes E2-1 to E2-4, may also have the same shape asthe sensing patterns SP2 shown in FIG. 6C.

According to some embodiments, a single line area of a conductive lineCL1 or CL2 shown in FIG. 6C may be defined at the boundary of the firstsensing electrodes E1-1 to E1-5 and the second sensing electrodes E2-1to E2-4. In the present disclosure, the conductive line CL1 and theconductive line CL2 may be referred as a first line CL1 and a secondline CL2, respectively.

Referring to FIG. 6C, first, second, and third openings IS-OPR, IS-OPG,and IS-OPB corresponding to first, second, and third color lightemitting areas PXA-R, PXA-G, and PXA-B may be defined in the sensingpattern SP2. The sensing pattern SP2 may include the first lines CL1overlapping the non-light emitting area NPXA and extending in a firstoblique direction CDR1 and the second lines CL2 extending in a secondoblique direction CDR2. The first lines CL1 and the second lines CL2intersect each other and may define the first, second, and thirdopenings IS-OPR, IS-OPG, and IS-OPB corresponding to the first, second,and third color light emitting areas PXA-R, PXA-G, and PXA-B. Thus, thesensing pattern SP2 may have a grid shape or a mesh shape. However, eachof the first lines CL1 may not be a perfect straight shape in the firstoblique direction CDR1 and may include a plurality of straight areas anda plurality of inflection areas. The second lines CL2 may also include aplurality of straight areas and a plurality of inflection areas.

The first line area LA1, the second line area LA2, thethird line area LA3, and the fourth line area LA4 may be arrangedparallel to the first edge E1, the second edge E2, the third edge E3,and the fourth edge E4, respectively.

The interval between a corresponding line area and a corresponding edgeis illustrated as the constant sensing pattern SP2 according to someembodiments, but embodiments are not limited thereto. When each of thefirst, second, and third color light emitting areas PXA-R, PXA-G, andPXA-B has a shape different from a corresponding opening among thefirst, second, and third openings IS-OPR, IS-OPG, and IS-OPB, theinterval between the line area and the edge may not be constant.

An intersection area CA may be arranged between the adjacent line areas.The intersection area CA may have a line width greater than at least anadjacent line area. It may be seen that the line width of the first linearea LA1 is compared with the line width of the intersection area CAdefined between the first line area LA1 and the third line area LA3.

FIG. 7A is a cross-sectional view illustrating a radiation path ofsource light. FIG. 7B is a graph illustrating the amount of change inlight intensity according to a viewing angle.

FIG. 7A schematically illustrates a display device DD shown in FIG. 6A.Source light generated by a light emitting element LD may be radiated toa front surface of the display device DD. A conductive pattern CP maycorrespond to a light shielding pattern which blocks source light. Thelight emitting shape of the source light may be deformed from a radialshape by the blocking of the conductive pattern CP.

Referring to FIG. 7B, a first graph GP10 and a second graph GP20illustrate the amount of change in light intensity (or optical power)according to a viewing angle. The first graph GP10 is measured in astate where a conductive pattern CP of FIG. 7A is omitted, and thesecond graph GP20 is measured in a state where the conductive pattern CPis located. Referring to FIGS. 7A and 7B, the conductive pattern CPlocated between a measurement point and a light source point maycorrespond to a light shielding pattern for source light. Alternatively,the more the viewing angle increases, the more the light shieldingeffect increases.

According to the present disclosure, WAD described with reference toFIG. 4 may be reduced using the light shielding function of theconductive pattern CP described with reference to FIGS. 7A and 7B. Adetailed description thereof refers to FIG. 8A below.

FIG. 8A is a plan view illustrating an arrangement relationship betweenlight emitting areas PXA-R, PXA-G, and PXA-B and a sensing electrode SEaccording to some embodiments of the present disclosure. FIG. 8B is agraph illustrating the amount of change in color coordinates accordingto a distance between a first color light emitting area PXA-R and asensing electrode SE according to some embodiments of the presentdisclosure.

The sensing electrode SE shown in FIG. 8A may be a portion of a sensingelectrode SP2 shown in FIG. 6C, which is illustrated in detail comparedwith FIG. 6C. Hereinafter, a detailed description of the same componentsas the components described with reference to FIG. 6C will be omitted.

An arrow shown in FIG. 8A refers to a direction facing the sensingelectrode SE from a measurement point where WAD described with referenceto FIG. 4 is measured (briefly referred as “the direction of themeasurement point of WAD” hereinafter). According to some embodiments,as described with reference to FIG. 4 , the measurement point where theWAD is measured may have a third azimuth angle ϕ30 and a fifth viewingangle θ5 (refer to FIG. 3 ). Furthermore, it is described that a reddishwhite image is measured. As will be described later, the measurementpoint where WAD is measured is located adjacent to a first area LA1 thanto a second area LA2.

The sensing electrode SE may include a first conductive line CL-Rdefining a first opening IS-OPR (refer to FIG. 6C), a second conductiveline CL-G defining a second opening IS-OPG, and a third conductive lineCL-B defining a third opening IS-OPB. Each of the first conductive lineCL-R, the second conductive line CL-G, and the third conductive lineCL-B may be formed by a combination of two first lines CL1 (refer toFIG. 6C) and two second lines CL2 (refer to FIG. 6C), which aredescribed above.

Each of the first conductive line CL-R, the second conductive line CL-G,and the third conductive line CL-B may include a first area LA1, asecond area LA2, a third area LA3, and a fourth area LA4 correspondingto a first line area LA1, a second line area LA2, a third line area LA3,and a fourth line area LA4 described with reference to FIG. 6C.Corresponding areas among the first to fourth line areas LA1 to LA4 andthe first to fourth areas LA1 to LA4 refer to the same referencenumerals.

A distance between a corresponding light emitting area PXA-R, PXA-G, orPXA-B and a corresponding line area LA1 or LA2 may be about 15 to 20micrometers. A distance B1 between the first color light emitting areaPXA-R and the first area LA1 may be less than a distance A1 between thesecond color light emitting area PXA-G and the first area LA1 and adistance A1 between the third color light emitting area PXA-B and thefirst area LA1. The first color light emitting area PXA-R and the firstarea LA1 may be arranged relatively close to each other such that lessfirst color light is provided in the direction of the measurement pointof WAD. The distances A1 and B1 may be measured by a criterion such as adistance LR shown in FIG. 6A. In other words, like the distance LR shownin FIG. 6A, an interval (e.g., distance Lr) between an edge PDL-E of apixel definition layer PDL defining the light emitting area PXA and anedge of a conductive pattern included in a second conductive patternlayer 200-CL2 may be measured as a distance (e.g., distances A1 and B1).

The first area LA1 extending in a direction perpendicular to thedirection of the measurement point of WAD may shield first color lightin the direction of the measurement point of WAD. When the measurementpoint of WAD is defined as a first point (r1, θ1, ϕ1), a verticaldirection (i.e., the direction perpendicular to the direction of themeasurement point of WAD) may be a direction where a second point (r1,θ1, ϕ1+180° and a third point (r0, θ1, ϕ1−90° are connected with eachother.

A line width WB of the first area LA1 of the first conductive line CL-Rmay be greater than a line width WA of the first area LA1 of the secondconductive line CL-G and the third conductive line CL-B. The line widthWB of the first area LA1 of the first conductive line CL-R may begreater than a line width WA of second to fourth areas LA2 to LA4 of thefirst conductive line CL-R. The second conductive line CL-G and thethird conductive line CL-B may have the same line width WA irrespectiveof the first to fourth areas LA1 to LA4.

Further increasing the line width of the specific area to increase lightshielding efficiency in the specific direction is described as anexample according to some embodiments, but a line thickness of thespecific area may increase to increase light shielding efficiency in thespecific direction.

When less red source light is provided toward the measurement point ofWAD, as the amount Δu′ of change of color coordinates u′ described withreference to FIG. 4 is reduced, a WAD phenomenon may be reduced. Forexample, a thickness of the first area LA1 of the first conductive lineCL-R adjacent to the first color light emitting area PXA-R may begreater than a thickness of the first area LA1 of the second conductiveline CL-G adjacent to the second color light emitting area PXA-G and athickness of the first area LA1 of the third conductive line CL-Badjacent to the third color light emitting area PXA-B.

FIG. 8B illustrates five simulation results. Referring to FIGS. 8A and8B, unlike FIG. 8A, in a first graph GP100 and a second graph GP200, adistance B1 between the first color light emitting area PXA-R and thefirst area LA1, a distance A1 between the second color light emittingarea PXA-G and the first area LA1, and a distance A1 between the thirdcolor light emitting area PXA-B and the first area LA1 are measured inthe same condition. The first graph GP100 is measured at a first azimuthangle ϕ100, and the second graph GP200 is measured at a second azimuthangle ϕ200. The second azimuth angle ϕ200 may be greater than the firstazimuth angle ϕ100 by 45°. The first azimuth angle ϕ100 may be the sameas a second azimuth angle ϕ20 of FIG. 4 , and the second azimuth angleϕ200 may be the same as a third azimuth angle ϕ30 of FIG. 4 . Third tofifth graphs GP301 to GP303 indicate the amount of change in colorcoordinates of a display device shown in FIG. 8A. The fourth graph GP302is measured under the condition that the distance B1 between the firstcolor light emitting area PXA-R and the first area LA1 is less than thatin third graph GP301 by one micrometer. The fifth graph GP303 ismeasured under the condition that the distance B1 between the firstcolor light emitting area PXA-R and the first area LA1 is less than thatin the fourth graph GP302 by one micrometer. The third to fifth graphsGP301 to GP303 are measured at the second azimuth angle ϕ200.

Four measurement points P1 to P4 may have different viewing angles θ. Asgoing from first measurement point P1 to the fourth measurement pointP4, the viewing angle θ increases.

Referring to third to fifth graphs GP301 to GP303 and FIG. 8A, it may beseen that the closer the distance B1 between the first color lightemitting area PXA-R and the first area LA1, the more the coordinates ofthe amounts Δu′ and Δv′ of change in color coordinates measured at thefourth measurement point P4 having the largest viewing angle change tothe left. This is because the closer the first color light emitting areaPXA-R (refer to FIG. 8A) and the first area LA1 (refer to FIG. 8A), themore the light shielding efficiency of the first area LA1 increases.

It may be seen that the coordinates of the amounts Δu′ and Δv′ of changein color coordinates at the fourth measurement point P4 of the fifthgraph GP303 deviate from a reddish white area and are close tocoordinates of the amounts Δu′ and Δv′ of change in color coordinates atthe first measurement point P1. The closer the distance B1 between thefirst color light emitting area PXA-R and the first area LA1, the morethe light shielding effect increases and the more the amount of changein color coordinates decreases.

Referring again to FIG. 8A, the distance B1 between the first colorlight emitting area PXA-R and the first area LA1 may be less than thedistance A1 between the first color light emitting area PXA-R and thesecond area LA2. By comparison, the distance A1 between the second colorlight emitting area PXA-G and the first area LA1 may be the same as thedistance A1 between the second color light emitting area PXA-G and thesecond area LA2. The distance A1 between the third color light emittingarea PXA-B and the first area LA1 may be the same as the distance A1between the third color light emitting area PXA-B and the second areaLA2. The distance A1 between the first color light emitting area PXA-Rand the second area LA2 may be substantially the same as the distance A1between the second color light emitting area PXA-G and the second areaLA2 and the distance A1 between the third color light emitting areaPXA-B and the second area LA2.

There is an azimuth angledifference of 90° between two points adjacent to each other among fourpoints. The four points may include a first point (r1, θ1, ϕ1) adjacentto the first area LA1, a second point (r1, θ1, ϕ1+180°) adjacent to thesecond area LA2, a third point (r1, θ1, ϕ1−90° adjacent to the thirdarea LA3, and a fourth point (r1, θ1, ϕ1+90° adjacent to the fourth areaLA4.

A first color light emitting area PXA-R is illustrated on behalf oflight emitting areas PXA-R, PXA-G, and PXA-B in FIG. 9A. The first colorlight emitting area PXA-R may have a circular shape or an oval shape.

A distance B1 between a first area LA1 and the first color lightemitting area PXA-R may be non-uniform. Each of a second area LA2, athird area LA3, and a fourth area LA4 may have a non-uniform distancefrom the first color light emitting area PXA-R.

A distance B1 and A1 between the first area LA1, the second area LA2,the third area LA3, and the fourth area LA4 and the first color lightemitting area PXA-R may be measured as the shortest distance. Thedistance B1 between the first area LA1 and the first color lightemitting area PXA-R may be less than a distance A1 between the otherareas and the first color light emitting area PXA-R.

FIG. 9B illustrates embodiments where measurement points of WAD aredifferent from each other. An example in which a reddish white image ismeasured at a point of (r, 60°, 90°) is illustrated. According to someembodiments, to prove less red source light at an azimuth angle of 90°,a distance B1 between the first color light emitting area PXA-R and thefirst area LA1 and a distance B1 between the first color light emittingarea PXA-R and the third area LA3 may be less than a distance A1 betweenthe first color light emitting area PXA-R and the second area LA2 and adistance B1 between the first color light emitting area PXA-R and thefourth area LA4. The distance A1 between the second color light emittingarea PXA-G and the third area LA3 and the distance A1 between the thirdcolor light emitting area PXA-B and the third area LA3 may be the sameas the distance A1 shown in FIG. 8B. That is, the distance B1 betweenthe first color light emitting area PXA-R and the third area LA3 isequal to the distance A1 between the second color light emitting areaPXA-G and the third area LA3 and the second color light emitting areaLA3. It may be smaller than the distance A1 between the third colorlight emitting area PXA-B and the third area LA3.

Unlike the presence of one area (e.g., the first area LA1) most adjacentto the measurement point of WAD in the embodiments described withrespect to FIG. 9A, there are two areas (e.g., the first area LA1 andthe second area LA3) having the same condition with respect to themeasurement point of WAD in the embodiments described with respect toFIG. 9B. To reduce WAD, both the first area LA1 and the third area LA3are arranged closer to the first color light emitting area PXA-R.

Referring to FIG. 9C, WAD may be measured at two or more points.According to some embodiments, two WAD measurement points areillustrated by arrows. The first measurement point may be the same as ameasurement point of FIG. 8A.

A design of a sensing electrode SE may be changed based on the secondmeasurement point. A distance between any one of the second color lightemitting area PXA-G and the third color light emitting area PXA-B andany one of the second to fourth areas LA2 to LA4 may be less than adistance between the other of the second color light emitting area PXA-Gand the third color light emitting area PXA-B and the any one of thesecond to fourth areas LA2 to LA4. Furthermore, the distance between theany one of the second color light emitting area PXA-G and the thirdcolor light emitting area PXA-B and the any one of the second to fourthareas LA2 to LA4 may be less than a distance between the first colorlight emitting area PXA-R and the any one of the second to fourth areasLA2 to LA4.

Hereinafter, measuring a bluish white image at the second measurementpoint having coordinates of (r, 60°, 225°) is described as an example.To prevent or reduce instances of WAD generated at the secondmeasurement point, a distance Cl between the third color light emittingarea PXA-B the fourth area LA4 may be less than a distance A1 betweenthe first color light emitting area PXA-R and the fourth area LA4 and adistance A1 between the second color light emitting area PXA-G and thefourth area LA4. The third color light emitting area PXA-B and thefourth area LA4 may be arranged close to each other such that less thirdcolor light is provided toward the second measurement point. A linewidth WC of the fourth area LA4 adjacent to the third color lightemitting area PXA-B may be greater than a line width WA of the first tothird areas LA1 to LA3 adjacent to the third color light emitting areaPXA-B.

A distance Cl between the third color light emitting area PXA-B and thefourth area LA4 may be less than a distance A1 between the third colorlight emitting area PXA-B and the third area LA3. By comparison, thedistance A1 between the second color light emitting area PXA-G and thefourth area A4 may be the same as the distance A1 between the secondcolor light emitting area PXA-G and the third area LA3. The distance A1between the first color light emitting area PXA-R and the fourth areaLA4 may be the same as the distance A1 between the first color lightemitting area PXA-R and the third area LA3.

Inother words, each of the first sensing electrodes E1-1 to E1-6 and thesecond sensing electrodes E2-1 to E2-4 may include a plurality ofconductive lines which intersect each other to form a mesh.

According to some embodiments, a sensing area 200A may include aplurality of sensing units SU. All of the sensing area 200A may bedivided into the plurality of sensing units SU, or a portion of thesensing area 200A may be divided into the plurality of sensing units SU.

Each of the sensing units SU may have the same area. According to someembodiments, each of the sensing units SU may include a correspondingintersection area among intersection areas of the first sensingelectrodes E1-1 to E1-6 and the second sensing electrodes E2-1 to E2-4.

Each of the sensing units SU may include a half of sensing pattern SP1and the other half of sensing pattern SP1 arranged across the bridgepattern CP and may include a half of sensing portion SP2 and the otherhalf of sensing portion SP2 arranged across the middle portion CP2.

Referring to FIG. 10B, each of the sensing portions SP2 may includeextension portions SP2 a and SP2 b and branch portions SP2 c 1 to SP2 c4. The extension portions SP2 a and SP2 b may include the firstextension portion SP2 a which extends side by side along the firstdirection DR1 and the second extension portion SP2 b which is bent fromthe first extension portion SP2 a and extends across a second dummypattern DUP2. Meanwhile, the present disclosure is not limited thereto.The second dummy pattern DUP2 of some embodiments may not be locatedbetween the second extension portions SP2 b, and the second extensionportion SP2 b may extend in a direction parallel to the first extensionportion SP2 a.

Each of the branch portions SP2 c 1 to SP2 c 4 may extend along adirection away from the middle portion CP2 across the middle portionCP2. The branch portions SP2 c 1 to SP2 c 4 may include first to fourthbranch portions SP2 c 1 to SP2 c 4. The first branch portion SP2 c 1 andfourth branch portion SP2 c 4 may extend along a first intersectiondirection DRa, and the second branch portion SP2 c 2 and the thirdbranch portion SP2 c 3 may extend along a second intersection directionDRb. The first intersection direction DRa may be parallel to a secondoblique direction CDR2 shown in FIG. 6C, or an angle between acuteangles may be defined therebetween. The second intersection directionDRb may be parallel to a first oblique direction CDR1 shown in FIG. 6C,or an angle between acute angles may be defined therebetween.

The first intersection direction DRa may be defined as a directionintersecting each of a first direction DR1 and a second direction DR2.The second intersection direction DRb may be defined as a directionwhich is orthogonal to the first intersection direction DRa at the sametime as intersecting each of the first direction DR1 and the seconddirection DR2. Each of the first intersection direction DRa and thesecond intersection direction DRb may correspond to a diagonal directionbetween the first direction DR1 and the second direction DR2 on asurface defined by the first direction DR1 and the second direction DR2.

The first to fourth branch portions SP2 c 1 to SP2 c 4 may move awayfrom each other in opposite directions. For example, the first branchportion SP2 c 1 may move away from the second branch portion SP2 c 2 inthe first direction DR1 and may move away from the third branch portionSP2 c 3 in the second direction DR2. The first branch portion SP2 c 1may move away from the fourth branch portion SP2 c 4 across the middleportion CP2 in the first intersection direction DRa.

The middle portion CP2 may be located between portions which protrudetoward each other in the first direction DR1 of the sensing patternsSP1. The middle portion CP2 may connect between the first extensionportions SP2 a of the sensing portions SP2. The middle portion CP2 maybe integrally formed on the same layer as the first extension portionsSP2 a.

Each of the sensing patterns SP1 may include a first portion SP1 b whichextends along the first direction DR1 and a second portion SP1 a whichextends from the first portion SP1 b and surrounds one portion of thesensing portions SP2. The second portion SP1 a of the sensing patternsSP1 may surround branch portions SP2 c 1 to SP2 c 4 of the sensingportion SP2 located adjacent thereto. Referring to FIG. 10B, the secondportion SP1 a of the sensing pattern SP1 located at the left in thesensing unit SU may surround the first and third branch portions SP2 c 1and SP2 c 3, and the second portion SP1 a of the sensing pattern SP1located at the right may surround the second and fourth branch portionsSP2 c 2 and SP2 c 4.

The first portions SP1 b of the sensing patterns SP1 may be spaced apartfrom each other across the middle portion CP2 in the first directionDR1. The bridge pattern CP1 may electrically connect the sensingpatterns SP1 spaced apart from each other. FIG. 10B illustrates twobridge patterns CP1 arranged in the sensing unit SU. However, the numberof bridge patterns CP1 arranged in the sensing unit SU is not limitedthereto, which may be less or more.

As shown in FIG. 10B, the bridge patterns CP1 may be in the shape of abent line such as “A” or “v” on the plane. The bridge patterns CP1 inthe shape of the bent line may overlap the sensing portions SP2.However, the present disclosure is not limited thereto. The bridgepatterns CP1 may be in the shape of a straight line extending along thefirst direction DR1 and may overlap the middle portion CP2 on the plane.

Each of the dummy patterns DUP may be electrically floating patterns.Each of the dummy patterns DUP may be patterns insulated from the firstsensing electrodes E1-1 to E1-6 and the second sensing electrodes E2-1to E2-4. The dummy patterns DUP may include first to fourth dummypatterns DUP1 to DUP4 depending on an arrangement position.

The first dummy patterns DUP1 may be arranged between the first sensingelectrodes E1-1 to E1-6 and the second sensing electrodes E2-1 to E2-4.In detail, the first dummy patterns DUP1 may be arranged between thesensing pattern SP1 and the sensing portions SP2. For example, as shownin FIG. 10B, the first dummy patterns DUP1 may be arranged between thesecond portions SP1 a of the sensing pattern SP1 and the branch portionsSP2 c 1 to SP2 c 4 of the sensing portions SP2 to surround the branchportions SP2 c 1 to SP2 c 4.

As the first dummy patterns DUP1 are arranged between the sensingpatterns SP1 and the sensing portions SP2, mutual capacitance betweenthe sensing patterns SP1 and the sensing portions SP2 may be reduced.However, although the first dummy patterns DUP1 are arranged, the amountof change in mutual capacitance by occurrence of a touch event may notbe significantly reduced. Thus, an (amount of change in mutualcapacitance)/(mutual capacitance) value may be increased by the firstdummy patterns DUP1.

Thus, a ghost touch phenomenon which occurs in a specific environment bythe first dummy patterns DUP1 may be reduced. The ghost touch phenomenonrefers to a phenomenon where a noise signal rather than a signalactually generated by a touch event is amplified and recognized as atouch. For example, when a portion of the sensing area increases intemperature by an operation such as a touch event in a low-temperaturestate and when the entire sensing area is turned on, it may operate asif a touch occurs in an area in which a touch event did not occur in thesensing area. However, the ghost touch phenomenon may be reduced by thefirst dummy patterns DUP1, and reliability of the input sensor 200 maybe improved.

An interval between the sensing patterns SP1 and the sensing portionsSP2 may be increased by the first dummy patterns DUP1. A probabilitythat the sensing patterns SP1 and the sensing portions SP2 will beshort-circuited may be reduced. For example, an interval between thesensing patterns SP1 and the sensing portions SP2 may be a scale ofabout 4 μm to about 5 μm when the first dummy patterns DUP1 are notarranged, whereas an interval between the sensing patterns SP1 and thesensing portions SP2 may increase to a scale of about 70 μm or more whenthe first dummy patterns DUP1 are arranged. Thus, only when foreignsubstances or residues of about 70 μm or more should occur in an areawhere the first dummy patterns DUP1 are arranged, the sensing patternsSP1 and the sensing portions SP2 may be short-circuited.

The first dummy patterns DUP1 may include a plurality of patternselectrically insulated from each other. The plurality of patterns mayvary in size with the sensing unit SU with regard to mutual capacitanceand visibility. However, the embodiments of the first dummy patternsDUP1 are not limited thereto.

The second dummy patterns DUP2 may be surrounded by the second extensionportion SP2 b of the above-mentioned sensing portion SP2. The thirddummy patterns DUP3 may be surrounded by the sensing pattern SP1. Thefourth dummy patterns DUP4 may be arranged between the first sensingelectrodes E1-1 to E1-6 arranged along the second direction DR2 in FIG.10A. Meanwhile, according to some embodiments, at least some of thefirst to fourth dummy patterns DUP1 to DUP4 may be omitted.
